Question:

How do I convert a string into an Integer?


[Print this FAQ]

Answer: Due to changes in VB.NET and C#, when programming ASP.NET Web pages, developers must be aware of a variable's data type. Oftentimes, trying to assign a String variable to a variable of type Integer will result in a "Type Mismatch" error.

To successfully convert a String into an Integer, you can use one of two techniques: via the Parse method of the Int32 class

// C# code
String sNumber = "123";
int iNumber = Int32.Parse(sNumber);

' VB.NET code
Dim sNumber as String = "123"
Dim iNumber as Integer = Int32.Parse(sNumber)

or via the Convert class:

// C# code
String sNumber = "123";
int iNumber = Convert.ToInt32(sNumber);

' VB.NET code
Dim sNumber as String = "123"
Dim iNumber as Integer = Convert.ToInt32(sNumber)
